DISK WHEEL.

Application led January 31, 1921.

le it known that l. (licentie ll. FonsyTH, a eitizen ot' the VnitedStates. residingr at llarvey. in the eounty ot' ('ook and State ofIllinois. have invented certain new and useful Improvements in Disk'heels. of which the following is a speeitieation.

iy reason ol'l the growing seareity of materials suitable l'oremployment in the making ol' wooden wheels and the rapid deteriorationol' the same under stress of weather and liability to damage by roughusage. they are eoniing into distavor; the wire wheel has manyobjeetionable features inherent in its manut'aeture and employment; thesteel wheel ot spoke or artillery type. while desirable t'rom solnepoints ot' view. is very expensive to manutaetnre` and not the mostetlieient in use; and while the steel disk wheel possesses manyadvantages over other types. the trade is slow to adopt the same byreason ot' the tart that it apparently requires a doingaway withprevious standards. and the saeriliee of mut'h labor and money expendedin the development ot' a partieular pattern of hub and rim adopted asstandard by dill'erent ear manutaeturers. Moreover. hundreds otAthousands oll ears now in use would be equipped with disk wheels were itnot that in doing so the ear owner would saeriliee the value oll hispresent wheels as an entirety and be required to purehase a new set ollwheels eomplete in all their parts inelnding hubs and rims.

Prominent among the objet-ts of the present invention are the adaptationof a disk steel wheel to the utilization in eonneetion therewith ol'prevailing standards of hub and rim strut-tures. whereby the one wheelis rendered suitable to adoption by dittel'ent rar manul'aeturers l'oruse upon partieular makes ol' ears. and the wheels are suseeptible ollapplieation to ears now in use without neeessitating the pnrehase of newhubs and rims'. .\s to this feature ol' the invention. this applieationis a eontinuation of my eopending applieation. Serial No, zftli.

further feature ot' the invention is the provision ol means l'orassembling the wheel with a demountable rirn in sut-h manner as toinsure aeeuraey ol' plaeement ot' the rim. an improved appearanee of theassembled wheel and rim. a self-adjusting relation be` tween the two inease ol' eareless assemblage. together with other advantages whit-h willSpecification of Letters Patent.

he made apparent as the invention is understood.

In order that the invention in its various aspeets may be readilyunderstood and appreciated hy those skilled in the art. preferred andmodified embodiments of the invention are set forth hereinafter by wayof deseription and exemplified in the aecompanylng drawings. preeiated.however, that the description and drawings are illustrative only and arenot to be taken in an unneeessarily limiting sense.

ln the drawings` Fig. 1 is a seetion through a disk wheel embodying theinvention. taken on the line l`1ot'lt`ig-2:

Png. 2 is a 'face view of the wheel; l* lgs. 3 and ,Jf are detail viewsin perspeetivel illustratingr two different eonstructions having to dowith wheel and rim assemh ing;

Pigs. 5 and 6 are detail seetional views illustrating the manner ot'assembling the wheel with straight Side rims: and

Fig. T is a detail seetional view illustrating the assemblage ot' thewheel with a elineher rim.

I llaving partieular referenee to the drawing by way ot illustrativedescription the ret'erenee numeral 11 designates the usual brake drumassembled with the ordinal-'v hul l2 h v means of bolts 13 passingthrough the drum and the huh flange ist. At 15 are shown in dotted linesthe wood s )okes of the ordinary artillery type of wheel.

Tn that type ot wheel the spokes are aeeonnnodated within the sparebetween two radially projeeting members one of whieh is usually integralwith the hub and ealled the hub flange. while the other is ea able otremoval and ealled the hub plate. n either ease they are platesassoeiated with the hub and that term is used. herein to designateeither one or both of the integral and re` movable members disposed infront ot' and at the rear ot' the spokes'. .\s shown in Fig. l the rearhub plate is formed as the brake drum 11. whereas in one ol' the frontwheels the plate would extend radially but little farther than the boltslil.

Mamifaeturers ot ears and wheels have their standard patterns of' hubsand it is to the advantage of the. trade that the same hub besuseeptible of use t'or both the wood It will be readilv ap-` llt) Wheeland the disk wheel. Similarly where the owner of a ear desires to changefrom wood to disk wheels milch less expense is involved it he can usethe lmbs of `his car instead of discarding the wheels as an entirety andpurchasing new wheels including hubs.

To enable standard hubs as designed for wood wheels to be utilized indisk wheel construction. I provide a filler member i6 for dispositionwithin the space between the front and rear hub plates ll and l-l. whichspace is provided for the accommodation ot' the spokes 15 of a woodwheel. and the metal disk 1T. having the peripheral tire-carrying tellyportion 1S. is secured to the forward hub plate or Harige ,l-l upon theinterposed filler member 16. the bolts 12% being used. as in the case otwood spokes. to clamp the hub plate or Hange 14 and the hub plate ordrum ll upon the inner portion of the disk 1T and the filler member lo..\dvantageously the filler member has a radially projecting skirt 19which serves as a` rear abutment for the most deeply dished portion ofthe disk inst beyond the hub plate.y greatly reinforcing the disk inthat region and. by reason ot` its extended hearing. increasing thehomogeneity of the wheel structure adjacent the hub.

The peripheral portion ol the disk is rear wardly bent to constitute atelly upon which is received the demountable rim QU. To further simulatethe appearance of tellythickness. the disk is bent rearwardly at 2l andthen extends in a substantially radial direction at QQ. the effect beingpresented ot' a flat ring about the wheel linst within the rim. as isclearly brought out in Fig. Q at 2Q,

ln a disk wheel adapted for use in connection with demountable rims asalso in a wood wheel of the demonntable rim type the outer t'aceof thetelly is slightly inclined to the wheel axis and along its rear edge isprovided with an outstanding inclined beaded portion Q3 upon which therear edge of the rim will ride. thus determining the. proper-positionol' the rim upon the wheel. ln cooperation with the inclined tace oicthe t'elly and the beaded portion Q3 shim nicmbers 24 are employedhaving wedge-like portions :5 Jfor entry between the Jtelly and' theJforward edge otl the rim. said `shims having associated therewitheither as integral or separate elements a body portion Ztl ex tendinginwardly ot the wheel along the telly portion 2;. while holls` 2T passthrough the shim element lo and the telly portion Q2 for the purpose ollforcing the shim inwardly beneath the rim with the result that the rimis rearwardly pressed against the beaded portion Jil and outwardly.being supported by its forward edge. upon the wedge-like portion 25.

1t not int'reipientl) happens. in tbc plac lation between the bolt anding of a demountable rim upon a wheel that more resistance is met withat one point than another and without care the rim will beunsynnnetrically positioned upon the wheel. A variation ot' a .slnallfraction ot F0 an inch will canse lateral friction on the tire and itsrapid wear.

ln order to insure the propel' positioning of the rim on the wheel lprovide an amount ot' resiliency or yielding in the rim-position- 75 ingmeans. whether in the wedging portion ot' the shim itself. or in thebody ot' the shim. or in the bolt connection between the shim body andthe telly.

ln Figs. l and 2 the body ot the shim is 80 shown as possessing a degreeof resiliency: in Fig. :i both the wedge portion in ot' the shim andalso' the body portion 29 are resilient: the quality ot' resiliency maybe incorporated in that t'orm olshim shown in 85 Fig. 4; in Fig. awedging shim member il() is shown which advantageonsly comprises a splitring extending entirely around the wheel used in connection withseparate shim bodies 3l of spring metal: the wedging shim 90 member 32of Fig. t3 is in the t'orm ot' a split ring extending entirely round thewheel and having inherent yielding qualities. used in connection withseparate unyielding shim bodies 33.

ln Fig. 5 the yielding shim body 3l is shown as associated with anattaching bolt :it having a shouldered portion 35 and an acorn nut liti.The shoulder 35 forms an abutment which limits the inward movement otthe shim body Ill.

ln the embodiment shown in Fig. 6 the unyielding shim body 32% is usedin connection with attaehing bolts 3T having acorn nuts 3H hollowed outto receive a spring 105 washer Sill whereby is provided a spring reshimbody.

By the provision ot' resiliency in the rim positioning means. as abovedescribed. after the nuts on the bolts are drawn home. there remainsstored up spring energy to torce the rim farther onto the telly. and asthe shim bolts about the wheel are drawn up in Succession this springaction will serve automatically to equalize pressure on the rim H5 atdifferent points to bring about the proper positioning of the rim.rFlins any looseness in the individual nuts which supposedly had beenscrewed up to their full limit. will become apparent upon the completionof the job. and guard against improper placement ofthe rim.

in Fig, ii. it will he observed that the bod).1 L'tl oi' the shim isseated within a recess of' the side portion '32 ofl the telly. whereby a|25 substantially tlnsh telly surl'ace is provided. adding to thcappearance olI the wheel.

ln Fig. l that portion of the telly immediately uiulerlying t ie rin! isrecessed to receive the wedge portion Ylli olI the shim nhilc 13() titlthe body portion 41 overlies the flat portion 22 of the telly. Thisenables the wedging inclination ot the telly tace to be eoniined to thereeessed portion 4Q leaving the greater portion ot' the lelly underlyingthe rim at. 18 to be substantially parallel to the rim, thus avoidingthe usual gap at 43 around the wheel beneath the forward edge of the rimtor the entry ot water` mud. ete.

ln Fig. T the presenee ot a gap tor the ad mission ot water and the likeis guarded against by extending the parallel relation ot the Jtelly andrin1 forwardly beyond that shown in Figs. 1. $3, 5 and G and thenproviding a fillet at 44 bringing the metal ot" the disk baek to theplane of the portion 22.

l. The eombination with a standard hnb eonstrnetion ineluding anintegral hub flange and a removable hub plate 'spaced apart toaccommodate spoke ends therebetween` ota filler member disposed withinsaid spaee. and a metal disk secured to the hub flange upon the fillermember and having a peripheral tire-earrying portion. whereby to utilizethe Standard wood wheel hub in a metal wheel eonstrnetion. the fillermember having a portion radially extending behind and serving as a rearabutment t'or that portion of the disk adjaeent the flange.
